"I know my tuna, therefore I make the best effing tuna sandwich. I butter the bread to within an inch of its life and then fry the whole thing in a skillet until the cheddar melts into a cheesy river and the bread is basically a giant buttery cracker," writes Chrissy Teigen in her new cookbook, Cravings. Teigen is also crushing it on the cover of SELF magazine this month—read her full interview here.

But back to that tuna sandwich. Check out the supermodel-turned-cookbook-author's ooey, gooey recipe below.

Spread one tablespoon of butter on one side of each piece of bread, then flip the slices over so they are buttered-side down. Divide the tuna mixture between two slices of bread, then top with the tomato slices and cheddar. Place the remaining two slices of bread on top, buttered-side up.

Heat a heavy skillet over low heat and toast the sandwiches in it until the cheese is melted and the bread is golden and toasty, five to six minutes per side.
